Python，Error/Bug，输出打印两次，def/function

Question

[更新]我看到roomidea（）在两个不同的位置被调用：

定义价格（）： sBedsize，sRoomview，sVehicle，iRoomnum，iNights=roomidea（） 和 sBedsize，sRoomview，sVehicle，iRoomnum，iNights=roomidea（）

但问题是，每当我删除def price（）下的一个位置时：它都会导致一个错误，即iNights未定义它定义的位置，而只是在first def下定义的位置。你知道吗

我现在的问题是，每当我在pycharm中运行我的程序时，它会打印两次输入，现在我有了一些关于为什么会发生这种情况的想法，但是每当我试图解决这些想法时，它要么不起作用，要么会导致更多的错误或问题。现在我有一个函数里面的输入，我稍后会调用这个函数，现在我不知道我是否会调用它两次，因为我的第二个def里面也有回调，这个def是price，但是如果你看了告诉我，我会很感激的。你知道吗

Answer 1

你可能需要考虑更好的逻辑。问题是， 因为您使用的是方法sBedSize, sRoomview, sVehicle之外的def price():，所以它可能会崩溃。从price()返回

return sBedsize, sRoomview, sVehicle, iRoomnum, iNights, dPrice1, dPrice2, dPrice3, dPrice4, dPrice5, dResortfee1, dResortfee2, dTotalqs, dTotalqa, dTotalqsv, dTotalqav, dTotalks, dTotalka, dTotalksv, dTotalkav, dTaxqs, dTaxqa, dTaxqsv, dTaxqav, dTaxks, dTaxka, dTaxksv, dTaxkav, dOverallqs, dOverallqa, dOverallqsv, dOverallqav, dOverallks, dOverallka, dOverallksv, dOverallkav

sBedsize, sRoomview, sVehicle, iRoomnum, iNights, dPrice1, dPrice2, dPrice3, dPrice4, dPrice5, dResortfee1, dResortfee2, dTotalqs, dTotalqa, dTotalqsv, dTotalqav, dTotalks, dTotalka, dTotalksv, dTotalkav, dTaxqs, dTaxqa, dTaxqsv, dTaxqav, dTaxks, dTaxka, dTaxksv, dTaxkav, dOverallqs, dOverallqa, dOverallqsv, dOverallqav, dOverallks, dOverallka, dOverallksv, dOverallkav = price()

#sBedsize, sRoomview, sVehicle, iRoomnum, iNights = roomidea()
